public CurrentTimestamp()

Method Details

evaluate

public Object evaluate(List<Object> args)

The statement's clock in the session's zone, as live's TIMESTAMP_LTZ carries it.

Specified by:

evaluate in class BuiltInFunction

Parameters:

args - the optional fractional-seconds precision, which types the call but leaves the value at full precision

Returns:

the statement's clock

getMinArgCount

public int getMinArgCount()

Description copied from class: BuiltInFunction

The fewest arguments a call to this function may pass; fewer is an argument-count error.

Specified by:

getMinArgCount in class BuiltInFunction

Returns:

the minimum accepted argument count

getMaxArgCount

public int getMaxArgCount()

Description copied from class: BuiltInFunction

The most arguments a call to this function may pass; Integer.MAX_VALUE marks a variadic function (see BuiltInFunction.isVariadic()).

Specified by:

getMaxArgCount in class BuiltInFunction

Returns:

the maximum accepted argument count
